1. Method for filtering a sensor signal, comprising
providing a time-discrete sensor signal (ZS) as an input signal (ES),
generating an output signal (AS) via continuous filtering of the input signal (ES) using a time-discrete filter (ZF) in the time domain, which performs the following filter steps for each value of the input signal (ES):
comparing a specified signal value (BW) of a specified time index of the input signal (ES) with two further signal values (VW, NW) of the input signal (ES), wherein a first signal value (VW) of the two further signal values (WV, NW) is temporally prior to the specified signal value (BW) and wherein a second signal value (NW) of the further signal values (VW, NW) is temporally after the specified signal value (BW),
in the event that the specified signal value (BW) lies within the value interval spanned by the two further signal values (VW, NW), retaining the specified signal value (BW) unchanged at the specified time index,
in the event that the specified signal value (BW) is not within the value interval spanned by the two further signal values (VW, NW), replacing the specified signal value (BW) in the output signal by a new value.
